I have p8z77-v deluxe MB with corei7-3770K chip and 16Gb RAM. Installed all the updated drivers from asus web site. When go to the intel graphics module, under the multi-display options, only single display option exists. I was recently playing with new dell laptop, and went to the same menu, and it had other options for multi-display fromat (extended....). Mine only has one display option. Now, I only have 1 dispaly connected so far, but do I need to connect other monitors to see those options?
I did enable multi-disply in the BIOS, rebooted, but that did not change anything.
